Horizontal mount so needs a working ADBV

Minuscule little filter but it would seem that since the engine is super clean inside it didn't matter anyway.

ADBV super hard and not pliable at all rather like PVC making me think I probably lost a psi or 2 in back-pressure there already blush

Pleats nice and uniform with no tears.............

Sure feels like a solid filter.

Replaced with a FRAM PH5911 equivalent..................
